Nails can cause trouble for some. If you nail having healthy nails (Got that?), you’ve already done half of the job. For keeping your nails perfectly healthy avoid trimming them, and use a file instead. This will help you protect them as well as your cuticles. Keep them as round as possible because that shape is less likely to break. Also, make sure to have a balanced diet. Great nails, hair, and skin come as some of the benefits of a balanced diet!
